第二棱镜片150具有多个第二种三角棱镜。 The second prism sheet 150 has a second plurality of triangular prisms. 该第二种三角棱镜形成在一第二透明膜上,并沿预定图案排列。 The second triangular prism is formed in a second transparent film, and are arranged in a predetermined pattern. 第二棱镜片160设置在该第一棱镜片150上。 The second prism sheet 160 disposed on the first prism sheet 150. 该第二种三角棱镜的顶角经过圆化处理或处理使其具有圆形顶角。 The second triangular prism through the rounded apex or treated so as to have a round apex. 第二棱镜片160接受该第一次汇聚光,使其被第二次汇聚,并输出该第二次汇聚光。 The second prism sheet 160 converging light to accept the first, second that it is converged, and outputs the second convergent light.

当第一棱镜片150的第一棱镜沿第一方向布置时,第二棱镜片160的第二棱镜沿第二方向布置,该第二方向相对该第一方向有一预定角度,如90度。 When the first prism of the first prism sheet 150 is disposed in a first direction, a second prism sheet 160 is disposed a second prism along a second direction, the second direction opposite the first direction having a predetermined angle, such as 90 degrees. 从而,由该光导板110输出的光可沿光导板110的横向和纵向汇聚,以提供足够的视角。 Thereby, the light output from the light guide plate 110 may be brought together laterally and longitudinally along the light guide plate 110 to provide a sufficient viewing angle.

在上述范例中,公布了一种LCD,其中多个精细点形成在光导板110的光反射面112上,以有利于该被引导的光的漫反射。 In the above example, it discloses a LCD, wherein the plurality of fine dots formed on the light reflection surface 112 of the light guide plate 110, to facilitate the diffuse reflection light is guided. 在另一范例中,光导板110还可包括其上的散射片145。 In another example, the light guide plate 110 may further include a diffusion sheet 145 thereon. 在又一范例中,光导板110的光反射面112可被处理以具有一镜面或一镜面处理面(一种被处理的面,光滑或呈镜面状),而一漫反射部件可安装于光导板110的光发射面116上。 In yet another example, the light reflecting surface of the light guide plate 110, 112 may be processed (surface one processed, the smooth or mirror-like) to have a mirror or a mirror-finished surface, and a diffuse reflection member may be mounted to the light guide light emitting surface 116 on the plate 110. 漫反射发生在该漫反射部件上。 Diffuse reflection occurs on the diffusely reflective part. 在再一范例中,光导板110的光反射面112可被镜面处理,而光导板110还可包括其上的散射片。 In another example, the light guide plate 112 may be a light reflecting surface 110 of the mirror surface treatment, and may further include a light guide plate 110 on which the diffusion sheet.

LCD面板组件200包括:下衬底210,其上,薄膜晶体管(TFT)开关器件布置在一矩阵结构中;上衬底220,其上布置有与该TFT开关器件对应的红色(R)、绿色(G)和蓝色(B)的彩色滤光片;以及,液晶层,间插于下衬底210与上衬底220之间。 LCD panel assembly 200 comprising: a lower substrate 210 on which a thin film transistor (TFT) switching devices are arranged in a matrix structure; on the substrate 220, there is disposed a red (R) corresponding to the switching device TFT thereon, the green (G) and blue (B) color filter; and a liquid crystal layer interposed between the lower substrate 210 between the substrate 220 and the upper. LCD面板组件200响应由背光组件100提供的光而显示图像。 LCD display panel assembly 200 in response to the light from the backlight assembly 100 provides an image. 由于LCD面板组件200对本领域技术人员而言是熟知的,因此略去了对LCD面板组件200的详细描述。 Since the LCD panel assembly 200 to those of ordinary skill in the art is well known, a detailed description is omitted for the LCD panel assembly 200.

另外,LCD面板组件200还包括:防炫目偏振板230,其布置在下衬底210的后面;以及,上偏振板240,其布置在上衬底220上。 Further, the LCD panel assembly 200 further comprising: anti-glare polarizing plate 230, which is disposed behind the lower substrate 210; and a, upper polarizing plate 240, which is disposed on the upper substrate 220.

防炫目偏振板230的后面被处理,以具有一防炫目表面,或该后面被进行防炫目处理,使得防炫目偏振板230的后面具有预定的能见度(haze)的值。 Anti-glare rear polarization plate 230 is processed to have an anti-glare surface, or the back is subjected to antiglare treatment, so that the anti-glare rear polarizing plate 230 having a predetermined visibility value (Haze) of. 如上所述,防炫目偏振板230形成在下衬底210的后面,由背光组件100提供的光被防炫目偏振板230调制成具有均匀的偏振面,并且该具有均匀偏振面的光被提供至下衬底210。 As described above, anti-glare polarizing plate 230 is formed behind the lower substrate 210, the light provided from the backlight assembly 100 is modulated antiglare polarizer plate 230 to have a uniform polarization plane, and the light having a uniform polarization plane is supplied to the the substrate 210. 防炫目偏振板230可包括具有各种能见度值的树脂,如12%、25%、44%等。 Anti-glare polarizing plate 230 may include a resin having various visibility value, such as 12%, 25%, 44% and so on. 防炫目偏振板230对由背光组件100提供的光进行偏振,使得均匀的光入射至LCD面板组件200的下衬底210上。 Anti-glare polarizing plate 230 provides light from the backlight assembly 100 is polarized, so that a uniform light is incident on the lower substrate 210 LCD panel assembly 200.

该能见度值(H)可通过如下的方程1计算。 The visibility value (H) 1 may be calculated by the following equation.

方程1H=[H2/(H1+H2)]×100%其中,H1为当光入射至防炫目偏振板230时,沿着与入射方向相同的方向穿过防炫目偏振板230的光的亮度,而H2为由防炫目偏振板230散射后的光的亮度。 Equation 1H = [H2 / (H1 + H2)] × 100% wherein, Hl is the anti-glare when light is incident to the polarizing plate 230, the incident direction in the same direction through the anti-glare brightness of light polarizing plate 230, H2 by the anti-glare polarizing plate 230 after the luminance of the light scattering.

上偏振板240布置在上衬底220上,由于上偏振板240的存在,穿过上衬底220的光具有均匀的偏振面,并且该具有均匀偏振的光朝向LCD面板组件200射出。 Upper polarizing plate 240 disposed on the upper substrate 220, due to the presence of the polarizing plate 240, the light passing through the substrate 220 having a uniform polarization plane, and which has a uniform polarization light emitted toward the LCD panel assembly 200.
